I've chatted with Sonos support on Twitter regarding my issue, but I am not entirely convinced by their answer.
Here is my setup:
- Two Sonos Play:1 stereo pairs, spread over four rooms.
- One Play:5 in the fifth room.
- I end up with three groups, group1 (stereo pair), group2 (stereo pair) and group3 (single stereo speaker).
If I say to my Google Home: "Play music on Sonos", "Play next on Sonos", "play previous on Sonos", I get responses like "OK, playing music on [name of the Sonos group name]" (I don't know how Google Home decides which one. Say, this is not a big deal...
However, if I say "set volume to 20% on Sonos" or "turn it up / down on Sonos", only the volume on one of the Sonos groups is changed. If I want to change the volume on all of the groups, I have to give the command for each group separately and specify the group name as part of the command.
Why such inconsistency in behavior? Why "play" command can trigger all of the Sonos groups at the same time but not the volume-related commands?
I am also noticing that "thumbs up" and "thumbs down" commands do not work, but this is less important to me at the moment.
Thanks for any thoughts.
